STOVE.

SPECIFICATION forming' part of Letters Patent No. 595,714, dated December 21, 1897. Application filed Aprn 28.1897. seria1N0.6s4,26s. (Nomoaei.)

To all whom t may concern,.-

Be it known that I, ANDREW P. JOHNSON, a citizen of the United States, residing at Brooten, in the county of Stearns and State of Minnesota, have invented a new and useful Stove, of which the following is a specification.

It is the purpose of the present invention to provide a stove for utilizing hay, straw, bagasse, and such like fuel which will combine all the advantages of ranges and cooking-stoves consuming coal as fuel, said stove being provided with a bake-oven and a reservoir for heating Water, said reservoir being so disposed as to temper and moderate the heat of the oven, whereby the baking can be controlled.

For a full understandingof the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacricing any of the advantages thereof, and to a full disclosure of vthe invention an adaptation thereof is shown in the accompanying drawings, in Which- Figure 1 is a perspective View of a stove constructed after the principles of this invention. Fig. 2 is a longitudinal section thereof. Fig. 3 is a top plan View, the magazine being omitted,the front portion of the hearth broken away, and the top removed and having its position indicated by dotted lines. Fig. 4 is a detail view of the cap closing the lower end of the magazine. Fig. 5 is a detail view in perspective, of a portion of the magazine showing a damper-controlled opening, the damper being moved so as to disclose the opening controlled thereby. Fig. 6 is a detail section showing the position of the damper when closing the draft-opening of the magazine.

Corresponding and like parts are referred to in the following description and indicated in the several views of the accompanying Adrawings by the same reference-characters.

In general appearance the stove is of ordinary construction and comprises an oven 1, top 2, and hearth 3, the top having the` usual stove holes for receiving the various utensils used in cooking. The oven has a communicating water-space at its top, bottom, and sides, forming a reservoir 4,which is supplied with water through a spout 5, inclining upwardly and rearwardly and communicating at its lower end with the rear wall of the reservoir, said spout being closed at its up- .ervoir to be converted into steam or otherwise utilized to temper the heat of the oven when baking. f

A hot-air space 9 is provided at the top, bottom, and rear of the reservoir .and is in communication, and the products of combustion,

hot gases, &c. pass therethrough and are utilized for cooking, baking, and heating the water. A plate 10 closes the upper end of the hot-air spacev and a plate 11 closes the lower end, and both of these plates have stovepipethimbles with which short lengths of stovepipe communicate, so as to connect the magazine12 with the hot-air space of the stove. The thimble of the plate 10 is located at one end and is closed by a damper 13, by means of which the hot air and gases are caused to circulate and pass into the space formed between the stove-top 2 and the upper plate of the reservoir. The thimble of the plate 11 is4 centrally disposed and is closed by a damper 14, by means of which the products of combustion are admitted into the lower portion of the hot-air space 9 and caused to pass through the space beneath the reservoir in the rear and over the top thereof, thence out through the stovepipe 15, communicating with a stovepipe-thimble provided on the stove-top 2 at the hot air and gases entering through the damper-controlled inlet 13 to pass over the course of the stove-holes before escaping through the stovepipel 15.

IOO

The magazine 12 is of cylindrical form and of desired diameter and height, and is placed upon the hearth 3, and is connected by short lengths of stovepipe with the thimbles of the plates 10 and 11, the pipe 17 connecting the upper portion of the magazine with the plate IO and the pipe 18 connecting the lower portion of the magazine with the plate 11. The magazine is closed at its lower end by a cap 19, removably fitted thereto and provided centrally with an arched support for maintaining the fuel at the proper distance above the cap, so as to provide for a free circulation of the air to support combustion. Irons 2O are secured to the cap at diametrically opposite points and provide grips or handles to facilitate the removal and handling of the cap 19,

, made necessary in the operation of the stove. The lower portion of the magazine has a series of openings in its sides which are closed by dampers 21, pivoted to the magazine at one side of the openings, and each having an eX- tension 22, to be engaged when it is required to open or close the damper. The free end of each damper is inwardly lianged or constructed with an inclined portion 23, notched at its lower end, forming a catch to engage with the lower side of the opening, so as to retain the damper in a closed position, the inclined portion engaging with the side of the magazine with sufficient friction to hold the damper open at any required point.

The magazine is disconnected from the stove and its cap removed to admit of it being charged with hay, straw, or other light fuel, and when filled is placed in position, as indicated in Fig. 1, and the fuel lighted. For cooking solely the opening controlled by the damper 14 is closed and the damper 13 is opened, thereby permitting the heat to circulate through the space formed between the top 2 and the upper plate of the reservoir. For baking the upper damper 13 is closed and the lower damper 14 opened, whereby the heat circulates through the hot-air space and out through the stovepipe 15. When baking, the water is drawn off from the reservoir 4 to the level of the spigot 8 by means of the latter. The walls of the oven are stiifened and strengthened by stay-bolts connecting them with the respective plates forming the reservoir,said stay-bolts being provided in sufficient number to attain the desired end.

Having thus described the invention, what is claimed as new is- 1. In a stove, an oven located Within the body and having a space surrounding it on four sides, plates subdividing the top, bottom and rear spaces, forming an upper, a lower and a back hot-air space and a waterspace, which, with the front space, surrounds the oven on the said four sides, and stay-bolts connecting the walls of the oven with corresponding plates forming the outer walls of the surrounding water-space, substantially as described.

2. In combination, a stove provided with an oven having a surrounding space, plates subdividing the said surrounding space into hot-air and water spaces, the latter surrounding the oven on four sides, and the former extending at the top, bottom and rear of the said water-space, a spout for supplying water to the water-space, extending through the hot-air space, a longitudinal partition dividing the upper portion of the hot-air space, a smoke-pipe having communication with the hot-air space upon one side of the longitudinal partition, and astraw-burner having damper-controlled communication at its upper end with the hot-air space upon the opposite side of the said longitudinal partition and like communication at its lower end with the lower portion of the hot-air space, substantially as set forth.

3. In a stove for burning straw and light fuel, a magazine having a draft-opening in its side, and a damper for closing the draftopening pivoted at one end to the magazine and having its opposite end formed with an inclined portion notched in its lower end, substantially as shown for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the `presence of two witnesses.

ANDREV P. JOHNSON.
